I need some information about the switches on a Bally nip it zipper flipper - pictured.
There are three switches, 2 normally closed and one normally open which are activated when the flippers close. I need to know what they do as I can only find one in the schematic. No doubt it’s there I just can’t see it!
I know one of the normally closed switches opens to kill the close relay when the zipper activates. I don’t know what the others are meant to do.
Currently the normally open one activates the release catch as soon as it closes. The means when the zipper closes it immediately opens again. I don’t know if this is a short or if something else is meant to prevent this but as it stands it doesn’t seem logical.
Any info? Thanks
